Smart Focus Companion
The Smart Focus Companion (SFC-1) is a digital tool designed to help students improve concentration and develop steady study routines. To make full use of the device, read carefully before your first session.
Step 1: Starting and Charging
Connect the SFC-1 to a power source. When the screen lights up, the device is running a short system alignment, during which it adjusts internal functions so the device can work properly. Once the alignment is finished, the screen will show the main menu.
Step 2: Selecting a Study Mode
The SFC-1 offers three preset modes: Focus Session, Short Pause, and Review Block.
• Focus Session supports long, concentrated work.
• Short Pause provides a quick break to avoid fatigue.
• Review Block helps you check key points learned earlier.
You can choose a mode by tapping the icons on the screen.
Step 3: Adjusting the Timer
Use the ARROW buttons to increase or decrease the time. If the display changes slowly, don’t worry — it may be performing auto-stabilizing, which ensures that the timer shows accurate values.
Step 4: During Use
Press Start to begin. When the time ends, the device will give a gentle vibration. This function is designed to avoid interrupting others around you.
Step 5: Checking Your Progress
Open the "Daily Report" page to view your total study minutes and suggested improvements based on your recent sessions.
If the device becomes unresponsive, restart it by holding the power button for 6 seconds.
